Hello Saaa,

C c;
C2 c2 = new C2;
C3 c3 = new C3;
c=c2;

auto dg = { return c.method(); };

c=c3;

I actually did it like this before :) Thanks
But like this I need to do the "c is null" checking within the function
literal.
I'm not sure how these function literals are implemented; will the size of
the function
have any impact on speed? Or does the compiler handle them like any other
function and just thinks of a name itself ?

No more than with normal functions.

Exactly. If you compile with DMD and the -v flag you can see what names it gives them.

Thanks!
